INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent. Patented Jan, 9, 1917,,

Application filed October 23, 1914. Serial No. 868,221.

To all whom it may concern Be it known that I, HUGO C. WELL, a subject of the Emperor of Germany, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Internal-(lombustion Engine, of which the following is a full, clear, and exact description.

My invention has for its object to provide an internal combustion engine with a valve sleeve having a port for the admission of air under pressure and an exhaust port, these ports being uncovered at the same time to force through the cylinder cool air under pressure to thoroughly cleanse the cylinder of products of combustion. In addition the valve sleeve has a port for the admission of a combustion mixture and an auxiliary air port for the admission of compressed air at the end of the suction stroke of the engine to improve and to increase the pressure of the combustible mixture in the cylinder.

Additional objects of the invention will appear in the following specification in which the preferred form of my invention is disclosed.

In the drawings similar reference characters refer to similar parts in all the views in which Figure 1 is a sectional elevation of an enginc showing my invention; Fig. 2 is a sectional fragmentary view of the valve sleeve; and Figs. 3, 4, 5 and 6 are diagrammatic views showing the relative positions of the ports at different periods in the cycle.

By referring to the drawings it will be seen that the cylinder 5 has an exhaust port 6, and air inlet port 7 and a port 8 for the admission of a combustible mixture. It will be noticed that the ports 6, 7 and 8 are in difi'erent zones. Disposed in the cylinder 5 for rotating coaxially therewith, there is a valve sleeve 9 having an air inlet port 10, an exhaust port 11, a port 12 for the admis' sion of a combustible mixture and an auxil iary air inlet port 13, the ports 10 and 13 being disposed in the same zone and the ports 10, 11 and 12 being disposed in difierent zones so that the port 11 will be disposed to uncover the exhaust port 6 in the cylinder, the port 12 will be disposed for uncovering the admission port 8 in the cylinder,

and the ports 10 and 13 will be disposed for uncovering the air port 7 in the cylinder.

As will best be seen by referring to the diagrammatic views illustrated in Figs. 3, l, 5 and 6 the valve sleeve 9 is provided with two ports of each type, that the valve sleeve 9 may be rotated half a revolution during each complete cycle of the engine. This timing of the ports, permits the valve sleeve 9 to uncover the air port 7 in the cylinder by the auxiliary air port 13 at the end of the suction stroke of the englue, and as the inlet 8 is closed by the valve sleeve 9 at the termination of the inlet port 12 therein. This introduces air into the cylinder making a better combustible mixture and also slightly increases the pressure of the combustible mixture. This position of the ports is illustrated in Fig. 3 of the drawings. The termination of the compression stroke is illustrated in Fig. 4 of the drawings, and the termination of the power stroke is illustrated in Fig. 5 of the drawings, where the port 11 uncovers the exhaust port 6 in the cylinder and the air port l0 uncovers the air port 7 in the cylinder. When the air under pressure is forced through the air port 7 in the cylinder and the air port 10 in the valve sleeve, the products of combustion with the air, are exhausted through the exhaust port 11 in the sleeve, and the exhaust port 6 in the cylinder. In this way the products of combustion are removed from the cylinder, and at the same time the cylinder is cooled.

Fig. 6 illustrates the termination of the scavenging stroke of the cylinder, the admission port 12 in the valve sleeve being about to open communication between the admis sion port 8 in the cylinder and the interior of the sleeve and as the port 8 is closed the port 7 is momentarily uncovered to permit the introduction of compressed air through the port 7 and the auxiliary air port 13 in the valve sleeve.

In the sleeve 9 there is a piston 14 to which is pivoted at 15, a pitman 16, this pitman 16 having a slot- 17 in which is movably disposed an arm 18 on a crank 19, a gear 20 being secured to the crank 19 and meshing with the gear 21 on the sleeve 9 which will be rotated when the engine is operated.

Having thus described my invention I claim as new and desire Patent:

1. In an internal combustion engine, a cylinder having a head and adjacent the head in different zones, a combustible mixture port, an exhaust port and an air port, a valve sleeve disposed coaxially with the cyl-' inder and having in different zones a combustible mixture port, an exhaust port and an air port for communicating with the first mentioned ports respectively, the exhaust and the air ports being positioned in the sleeve for uncovering the cylinder air and exhaust, ports simultaneously.

2. In an internal combustion engine, a cylinder having a, head and adjacent the head in different zones, a combustible mixture port, an exhaust port and an air port, a valve sleeve disposed coaxially with the cylinder and having in different zones a como secure by Letters bustible mixture port, an exhaust port and an air port for communicating with the first mentioned ports respectively, the exhaust and the air ports being positioned in the sleeve for uncovering the cylinder air and exhaust ports simultaneously, and means for forcing air under pressure through the air port into the cylinder.

3. In an internal combustion engine, a cylinder having in different zones a combustible mixture port, an exhaust port and an air port, a valve sleeve disposed coaxially with the cylinder and having in different zones a combustible mixture port, an exhaust port and an air port for communicating with the first mentioned ports respectively, the exhaust and the air ports being positioned in the sleeve for uncovering the cylinder air and exhaust ports simultaneously, and an auxiliary air port in the valve sleeve positioned for uncovering the air port in the cylinder at the termination of the suction stroke of the engine.

4. In an internal combustion engine, a cylinder having a head and adjacent the head in different zones, a combustible mixture port, an exhaust port and an air port, a valve sleeve disposed coaxially with the cylinder and having in different zones a combustible mixture port, an exhaust port, and an air port for communicating with the first mentioned port respectively, the exhaust and the air ports being positioned in the sleeve for uncovering the cylinder air and exhaust ports simultaneously, and means for forcing air under pressure through the air port into the cylinder, there being an auxiliary air port in the valve sleeve positioned for uncovering the air port in the cylinder at the termination of the suction stroke of the engine.

5. In an internal combustion engine, a cylinder having adj acentits head an inlet port, an exhaust port and an air port, a piston in the cylinder, valve means for commanding the ports, and means to operate the valve means to open the exhaust and air ports simultaneously and to open the air port independently of the exhaust port at the termination of the suction stroke of the piston.

In testimony whereof I have signed my name to this specification in the presence of the two subscribing witnesses.
